Hi, Murray,

OpenDKIM now has enough data to make some interesting observations
about signatures and MIME.
As far as MIME encodings go (only the "outermost" encoding was
counted), there was a pretty common theme:
binary failed 4% of the time
quoted-printable failed 4% of the time
7bit failed 7.7% of the time
base64 failed 7.8% of the time
8bit failed 14% of the time
16bit (?!) never failed (though there was only one attempt)
I expected 8bit to fail more for some reason.
Interesting figures. Especially the 16bit ;-)
As far as MIME parts go (again, only the "outermost" MIME type was
counted), most of them have about a 90-93% survival rate which is
about in line with general signature survival rates.
This still leaves the question open whether there is any relation
between MIME labelling and -content transfer encoding, or none at all.
Clarification: it was my intention to say:
[...] between MIME labelling and -content transfer encoding on one side,
and DKIM signature 'survival' on the other side. Or no relationship at all.
